Ask a basic knowledge about violin.

If you are in Beijing, you can buy the "Xue Ping" piano made in Hu Xueping. Suitable for ordinary piano learners. When it comes to price, it mainly depends on the person who makes the piano. If he is famous, the piano will be expensive. Of course, it depends on the texture of the piano. There must be a difference between cheap and expensive. As for 1000 or 2000, it is definitely different from 7000 or 8000. First of all, the sound effects are different. Secondly, the wood of the piano board is different. And some accessories are better than ordinary ones, such as bridge horse, strings and bow hair.

Your sister has studied for six years. If her level is above Grade 9, just buy a relatively good piano for four or five thousand. If she doesn't want to learn the violin, it doesn't have to be too expensive. My piano costs 4000 yuan.

When choosing a piano, you should play only one piece (that is, the one you play best), and then try it out in these selected pianos. Use the piano that feels best. Another trick is to play some tunes in the high position of the four-string (so), which can be a single paragraph (you can use the second paragraph of Harvest Fisherman's Song), and see which piano on the four-string is the strongest, purest and with the least noise. After that, make a comprehensive selection of piano accessories.
